天线是移动通信系统的关键硬件设备之一。随着移动通信技术的飞速发展，系统越来越复杂，对天线性能的要求也越来越高。LTE作为第三代通信技术（3G）的长期演进技术，必将在未来的一段时间内对现代通信产生更大的影响，因而对于天线的工作频段、带宽、波束等相关指标也提出了更高的要求。对LTE频段±45°双极化宽带天线单元进行组阵设计和仿真分析，结果表明了该天线阵列工作性能良好。

Antenna is one of the key components of mobile communication systems. With the fast development of mobile communication system,the system is more and more complex,which demands the performance of antennas with higher quality. LTE (long term evolution),as a long term evolution technology for the 3rd generation communication technology will surely have a greater influence on modern communication in the near future. Therefore,some stricter requirements,such as antenna's work band,bandwidth and beam were presented. The arraying design and simulation analysis of the ± 45° dual-polarized wide-band antenna element working in LTE band are carried out in this paper. The results show that the antenna array works perfect.
